This invention relates to new and useful im rovements in educationaldevices.

(gne object of the invention is to provlde an improved device foreducational purposes, and especiall for the teaching of reading.

Another oliject of the invention is to provide means for successivelyexhibiting and concealing indicia whereby the observers eye travels fromleft to right across the face of the machine.

Another object of the invention is to provide an exhibiting machinehaving an elongated window in its front wall and having l a strip orroll, with indicia or symbols printed thereon, so mounted within themachine that the entire strip may be displayed, line by line, throughthe window, and to provide means for operating panels which successivelyclose portions of the window to cover portions ci the indicia or symbolson the strip, and thereby force the pupils eyes to travel from left toright across the face oi the machine.

Another object oi the invention is to provide means or actuating thestrip or en,

hibitor to bring the next line of the same into view after the panelshave been operated.

Still another object oi the invention is to provide means whereby thepanels :may be operated rapidly enough to allow the word or words to bevisible only7 'for a moment, thus teaching the pupil to instantlyrecognize the wor l.

Figure 14 is a transverse sectional view oi tlie same and taken on line1& 14 of Figure lin the drawings the numeral 10 designates an uprightcasing having a bottom 1l and provided with a door 12 in its rear wallto permit the easy insertion or removal ot the rolls hereinaitermentioned.

A horizontally elongated sight opening or window 13 is provided in thefront wall of the casing near its top. Within thev casing, a removablesuppl roller 1l is mounted in standards l5 whic are secured to the doorof the casing and entend upwary within the same. The roller ifi carriesa strip or cloth, paper or other suitable material l@ on which isprinted a series of sentences or other educational indicia.

The strip i6 is passed upwardly and over an idler roller l? mounted instandards l5 and then over a spacer roller i8 which is mounted in thestandards above the elongated window 13. Friction rollers lll (Fig. 2)are mounted in hanger yohes l5 and each hanger has a spring-pressedplunger i6 entending upwardly therefrom. Each plunger has a sliding litin arms 17 which ext-end inwardly from the standards i5 whereby therollers are capable or a vertical movement but are held againsthorizontal displacement. The friction rollers ride on the spacer roller.i8 to hold the strip i6 tightly against the Same.

The end of the strip l@ is'then secured ic: y

and 14). Thus when the key engages the slot the strip 16 ma be woundaroun the roller, but the key wi l automatically disenga e itself fromthe roller when the strip .is ing rewound, as will hereinafter be exlained.

It will be seen that a portion o the strip 16 is held in close proximityto the sight opening of the spacer roller 18 and the idler roller 17,and that portion .is clearly visible therethrough. (Flg. 1.)

The words or sentences, rinted 011 the strip or chart 16 are so s acelengthwise of the strip that they may e successively and individuallydisplayed thru the openin responsive to a step-by-step actuatlon o thespacer roller. For positioning the first line of indicia so that it willbe exactly in alinement'with the windowa knob 10 is provided on'one endof the winding roller 19. Before the machine is started this knob isturned to adjust the strip in its proper position.

For exhibiting the words in each line in sequence and thereby forcingthe pupils eyes to travel from left to right, I provide three doors orpanels 21 (Figs. 3, 4, and 5). Each panel is secured to and carried by avertical rod 22, which is supported by a bearing 22. Each rod isconnected by a spring coupling 23 to a plunger 24. Each plunger isslidably mounted in a bearing `24 and is provided with a foot 25 whichis normally positioned in the path of a cam 26, mounted on a horizontalcam shaft 27, which is supported at its ends in the standards 15. A stepcushion 26 is secured on the bottom 11 below each plunger 24 to absorbthe shock when said plunger drops to its lowest position.

The cam shaft is provided with a lug 27 (Fig.12) on one end and this lugis engaged by a pin 28 on one side of a clutch 50 whlch is slidablykeyed on a stub shaft 29 (Figs. 1 and 12). The stub shaft 29 issupported in the side wall of the casing and carries a gear 28', whichis driven by a gear 29 on the shaft of an electric motor 30. The camsare disposed in stepped order so that the panels are opened and closedsuccessively. For instance, when the panel on the left is lowered(Fig. 1) to allow the first words of the line to be seen the middle andright hand anels are in their raised or closed position. s the left handpanel rises, the middle panel is lowered and the panel on the rightremains closed,or in its raised position, as is shown in Fig. 1. Then,as the middle panel rises to again shut the words ofi' from view theright hand panel lowers and the panel on the left remains in its topmostposition. Thus, only one third of each line is visible at a time. Thisis an important feature of the invention as it forces the pupil toinstantly recognize the words, as well as to accustom h1s eyes to travelacross the board from left to right (Fig. 1).

After each panel 21 has been operated once and the entire line has beenread, the spacer roller 18 is given a quarter turn to bring the nextline lnto view thru the opening 13. For actuating the spacer roller, onequarter of a turn after the successive operation of the three panels21,a star wheel 31 (Fig. 10) is mounted on one end of the shaft 18 of saidroller. The star wheel is provided with elongated radial slots 32, andhas its outer edge riding on a shoulder 33 of a cam disk 34. A pin 35mounted on the outer edge of the cam disk engages in the slots 32 togive the wheel a quarter turn each time the cam makes one completerevolution.

The cam disk 34 is loosely mounted on a stub shaft 36 (Figs. 2 and 10)supported in a bracket 37 extending outwardly .and rearwardly from oneof the standards 15. The

cam is provided with a lug 38, on its outer face near its center, in thepath of a pin 39' secured on the shaft 36, whereby the cam is revolvedby the shaft when the pin engages the lug.

The stub shaft carries a gear 40 at its inner end and this gear isdriven by a chain 41 extending upwardly from a reverse gearing 42,which, in turn, is driven by the cam shaft 27. Thus the stub shaftrevolves in the opposite direction from theI cam shaft andat the samespeed. Each time the cam shaft makes one complete revolution and each ofthe cams 26 has been operated to raise or lower its respective panel 21the pin 35 on the cam 34 engages one of the slots 32 in the-star wheelto turn the spacer roller 18, thereby bringing the next line of thechart 16 into alinement with the slot. The pin 35 on the cam ispivotally connected to a spring 36 which has its other end secured tothe side wall of the casing. Due to loose mounting of the cam on thestub shaft, the spring serves to jerk the cam around quickly when thepin passes the center line of the cam. This movement allows for animmediate change of lines of the chart before the opening. The starwheel is prevented from being given more than a quarter turn each timeby the friction caused by the engagement of the outer edge of the starwheel with the shoulder 33 on the cam. A gear 31 is secured on the rearof the cam disk 34 and revolves therewith, This vgear engages a gear 32mounted on the outer end of the shaft 19 of the winding roller.' Thegear 32 drives a friction clutch 33 on the shaft 19 and it is obviousthat each time the cam disk is revolved the winding roller is rotated,thereby taking up any slack in the chart 16.

For automatically cutting off the motor after the entire strip or chart16 has been displayed before the opening 13, the strip is provided withan elongated slot 43. (Figs. 8 and 9.) The idler roller 17 has a groovev olovious imanes it at one end which is elined with the slot d3. A latspring i pivoted .at 46 to a loracket i7 extending inwardly from one ofthe standards 15, has its upper end constantly riding against the faceof the chart 16. The lower end of the spring carries a Contact point d8which is held against a contact 49 to complete the circuit to the motor.lt is that as long as the upper end ot the spring is held outward hy thechart 16 the circuit to the motor is complete. However, as the chartnears its end the slot 43 in the saine passes over the groove ist toallow the Y upper end of the spring l5 to drop into said grows.,` Bue tothe pivotal mounting ot the spring the contact points e8 and e9 areted,therehy breaking the circuit and stopthe niotor.

For rewinding the carrying roller 14: l provide a horizontal rod (Figs.l and 2) 5l, at the of the casing. `The rod extends almoet the entirelength ci the casing and has ons end extending through the outer wall ofthe seine. The rod is slidahly supported hy the well or the casing andhy hearings 52 extending upwardly :troni the top of the standards i5.The inner end ci the rod is pivotally connected to a vertical har 53which is at 5ft to a hrachet 55 'on the standio {Figx 2). rlhe lower endof the har is provided with a foot 56 3) which carries s ilat spring 57.The spring straddles the clutch end it is obvious tlr t when the rod 51.is pulled outwardly the clutch will he disengaged from the cani shaft27. @n its side opposite the cern shaft, the clutch carries e pin 58which, when the clutch is shifted, engages a lug 59 on a gear li()mounted on the stuh shaft 29. The gear 60 drives a gear 3l on e stuhshaft 61', hy means of a chain The other end the stub shaft carries gear52 which drives a gear 68 on the er? the carrying roller, to rewind theer has heen displayed.

l d 'l carries a lug 63 which is in alinenient wit; a. contact pointGel, leading to the motor end depending from the top ofthe casing. lt isseen that when the rod 5l is pulled outwardly the lug 63 will strike theContact Sliend force it against a Contact 65 which will cornolete thecircuit to again start the motor which has heen stopped by the hrealringoi the contacts i8 and i9 due to the spring .45, dropping thru the slotd3 in the chart into the groove it oi' the idler roller. The shifting ofthe rod 51, as hereinheiore explained, shifts the clutch 5G, whereby thestrip is rewound on 'the roller.

The rod 51 also carries cams 66 which engage in slots 67 in the frictionroller plungers 16 to raise the same when the rod is pulled outwardly.Thus the friction rollers 16' are lifted from the spacer roller 18 whenthe chart is being rewound on the carrying roller. The carrying rollerlll is made removable are sepso thatv a chart containing diferentmaterial may replace the same. lit is to he clearly understood that theinvention is not to be limited to charts carrying educational indicia,such as words, phrases, arithmetic, or the like, hut a chart carryingadvertising nieterial can he inserted in the machine whereby the devicecan he used tor any form oi progressive advertising. The mounting ot theroller 1.4i is shown in detail in Figure 'l'. At one end the roller isprovided with a square socket 68 which receives the squared shaft 69.The other end ot' the shaft carries the gear 63 which is driven thru thegears 6l and 62 hy the chain 62.

rlhe other end of the roller has a circular here Zt which receives a pin73. The pin is supported in one ot" the standards l5 and a spring 70 isconned on the pin between a collar 71 on said pin and a casing 72secured on the outer side ot the standard. lt is olovious that thecarrying rollers may he easily inserted or removed hy depressing the pin73.

lt is not always necessary to operate the panels 21 when using themachine and it has been found that at times the machine may he used tobetter advantage hy eliminating the use of these panels. For swingingthe 'feet 25 et the plungers 2t out of the path ot the cerns 26 ilprovide wings 75 on the rear oi the plungers 24:. A horizontal rod 76slidably supported in the standard l5 has one end extending thru theouter wall of the casing l0. As shown in Fig. 1l, the rod is providedwith ngers 77 which, when the rod is pulled outwardly, engage the wingsto swing the feet out of the path ot the canas 26 due to the springcoupling 23. Should any oi the cams 26 he in such a position as toprevent its respective toot 25 from swinging hack to its normal positionwhen rod is again pushed inwardly, the spring coupling 23 would serve tohold said foot against the side otl the cani until the carn revolvesaround to a position which will allow said toot to spring into place inthe path oi said cani.
